Abstract
The utility model relates to a pull force sensor, which is characterized in that a protecting rod is arranged in a cylindrical straining body; retaining rings are arranged on the two ends of the protecting rod, and the distance between the retaining rings on the two ends of the protecting rod is larger than the distance between the two end surfaces of the cylindrical straining body. When the measuring force has the excess load, while extending, the two ends of the cylindrical stressing body can be obstructed by the retaining rings; the inner deformation of the cylindrical stressing body can be ensured within the range of the elastic deformation, and the cylindrical stressing body can be protected when the measuring force has the excess load.
Description
The utility model relates to a kind of pulling force sensor.
Existing pulling force sensor can't be protected response body when institute's pulling force of surveying occurring and overload.Excessive when the pulling force of being surveyed, when making the deflection of response body exceed the limit of its elastic deformation, response body can't resile, and the dynamometry in the time of will influencing sensor like this and reuse is accurate.If the stressed overload of sensor is excessive simultaneously, may draw bad response body, sensor is scrapped.
The purpose of this utility model is to provide a kind of pulling force sensor that the strain physical efficiency is protected when dynamometry is transshipped.
The utility model is realized by following technical scheme:
The utility model is by ears joint 1; monaural joint 6; sleeve 3; tubular response body 9; foil gauge 8; and cable 7 is formed; ears joint 1 links to each other with an end of sleeve 3; the two ends of the tubular response body 9 in sleeve 3 link to each other with monaural joint 6 with ears joint 1 respectively; four foil gauge 8 symmetries are attached to the outside of tubular response body 9; and 8 of foil gauges are formed a bridge circuit; cable 7 joins with this bridge circuit outside the pass-out sleeve of back; in tubular response body 9, be installed with a guard bar 2; the two ends of guard bar 2 are provided with back-up ring 4 and 5; back-up ring 4 and 5 s' distance is greater than the distance between tubular response body both ends of the surface, and the difference of back-up ring 4 and 5 s' distance and the distance between tubular response body 9 both ends of the surface is less than tubular response body 9 elastic deformation amounts' ultimate value.
The utility model is simple in structure, reliable, and security is good.
Description of drawings:
Fig. 1 is the utility model one embodiment front view.
Fig. 2 is the A-A cut-open view of Fig. 1.
Below in conjunction with embodiment the utility model is further specified:
As shown in Figure 1; other structures of this sensor are identical with the structure of known pulling force sensor; in tubular response body 9, pass a guard bar 2; the back-up ring 4 of guard bar 2 and one end is made one; after guard bar 2 passes tubular response body 9; by another back-up ring 5 that is threaded, after back-up ring 5 installs, must guarantee back-up ring 4 and 5 s' distance and the range difference between tubular response body 9 both ends of the surface ultimate value less than tubular response body 9 elastic deformation amounts.
